Performance

This international standard provides general information about secondary batteries used in PVES and the typical methods of test used for the verification of battery performance. This standard does not include specific information relating to battery sizing, method of charge or PVES design. NOTE: This standard is applicable to Lead-Acid and Nickel Cadmium cells and batteries. This standard will be amended to include other electrochemical systems when they become available.

Specifies marking, designation, dimensions, tests and performance requirements for portable sealed Nickel Cadmium small prismatic, cylindrical and button rechargeable single cells, suitable for use in any orientation.

Specifies marking, designation, dimensions, tests and performance requirements for portable sealed nickel-metal hydride, small prismatic, cylindrical and button rechargeable single cells, suitable for use in any orientation. This third edition cancels and replaces the second edition published in 2003 of which it constitutes a technical revision.

The standard specifies marking, designation, dimensions, tests and requirements for vented Nickel Cadmium prismatic secondary single cells where special provisions have been made in order to have partial or, under very specific conditions, full gas recombination.

The standard specifies marking, designation, dimensions, tests and requirements for large format lithium-ion secondary single cells and batteries used in Industrial Applications including Stationary applications.

The standard covers specifies marking, designation, dimensions, tests and requirements for sealed nickel-metal hydride prismatic secondary single cells.

The standard provides electrical and mechanical requirements for liquid-immersed distribution and power transformers, and autotransformers and regulating transformers; single- and polyphase, with voltages of 601 V or higher in the highest voltage winding, are set forth. It is basis for the establishment of performance, and limited electrical and mechanical interchangeability requirements of equipment are described, and for assistance in the proper selection of such equipment.

The standard covers electrical, dimensional, and mechanical characteristics, taking into consideration certain safety features, for current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control of equipment associated with the generation, transmission, and distribution of alternating current. The aim is to provide a basis for performance, interchangeability, and safety of equipment covered and to assist in the proper selection of such equipment. Accuracy classes for metering service are provided.

The recommended practice document provides recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, preassembly, assembly, and charging of VLA batteries. Required safety practices are also included. This document is applicable to full-float stationary applications where a battery charger normally maintains the battery fully charged and provides DC loads.

The guide was written to provide a relevant PV battery test procedure that can be used to evaluate battery performance and identify appropriate PV battery charging requirements. The document contains a tutorial on Lead-Acid battery technology, battery charging characteristics, and a laboratory test procedure to evaluate charge parameters and battery performance.
